This option allows for the safe use of distinct filesystem snapshots of games with some cores (e.g., DosBox). Keep in mind that with this option enabled, game changes won't be saved (the unique save folder will be deleted on exit) until you explicitly call the save (or share) function. Thus, you will need files like dosbox.conf along with the games to use some default behaviors with each new game session.
This feature introduces a new configuration option, `NonBlockingSave`, which allows background saving for large files. With this param the saving process will not block the main thread with all network sockets.
By default, it's enabled for the DosBox core.
Keyboard and mouse controls will now work if you use the kbMouseSupport parameter in the config for Libretro cores. Be aware that capturing mouse and keyboard controls properly is only possible in fullscreen mode.
Note: In the case of DOSBox, a virtual filesystem handler is not yet implemented, thus each game state will be shared between all rooms (DOS game instances) of CloudRetro.
Libretro cores are selected based on the file extensions of the ROMs. However, ROM file extensions are not unique across cores (e.g., .zip is used in both DosBox and MAME). To load a specific core correctly, it's necessary to place the corresponding ROMs in designated folders specified in the configuration. By default, you can use the keys from cores.list as the folder names, or you can specify your own custom folder names using the 'folder' parameter for each core.
The new hid option enables users to map a specific Libretro device (or multiple devices) to the input ports. For instance, this allows users to map a Multitap controller with the snes9x core.
Depending on the configuration param coreAspectRatio, video streams may have automatic aspect ratio correction in the browser with the value provided by the cores themselves.
